I think this guy needs to go on diet!
First one is ISO 400, 5 sec exposure, holding a my old manual flash and shooting through a piece of paper (same for the rest of them), f/36; it has lots of difraction but has the DOF I want, tripod, MD 100mm f/4 macro lens with 2 to 1 ex tube.
The rest use ISO 200 and f/22.
John.
